Trains are parked outside the train station in Munich, Germany, Wednesday, Nov. 15, 2023. A union representing German train is calling its members out on a 20-hour strike from Wednesday evening on as a rancorous round of pay negotiations with the country's main rail operator gets under way. The GDL union called on drivers, guards and others to walk off the job from 10 p.m. Wednesday to 6 p.m. Thursday. (KEYSTONE/AP Photo/Matthias Schrader)
